Application filed April 15,1905. Serial No. 255,708-

To all whom itmay concern:

Be it known that I, WILLIAM G. J OBLING, a citizen of the United States, residing at Ridgedale, in the county of Hamilton and State of Tennessee, have invented new and useful Improvements in Reversible Disk Flows, of which the following is a specification.

This invention relates to reversible disk plows, particularly to that kind of a plow shown in my Patent No. 769,167, being a plow which is reversed by swinging the draftanimals and the tongue around without turning the frame of the plow.

The present invention relates especially to the means for turning or reversing the disk,

for regulatin the line of draft of the furrowwheels, and or adjusting the same to pro or height. A novel form of scraper is a so shown. i

The plow is illustrated in the accompanyin drawings, in whioh igure 1 is a lan view of the same, partly broken away. Fig. 2 is a rear elevation of the parts shown in Fi 1. Fig. 3 is a detail showing the manner mounting the furrowwheel axles. Fig. 4 is a detail in elevation showing the lever adjustment to the furrowwheel axles. Fig. 5 1s a side elevation of the complete plow. Fig. 6 is a section onthe line .6 6 of Fi 1. Fig. 7 is a detail in side elevation of t e foot-latch and associated parts. Fig. 8 is a front view of the same parts. Fig. 9 is a bottom view of the latch. Figs. 10 and 11 are top and end views of the front end of the cam. Fig. '12 is a detail sectional lan showing parts of the reversing-gear. igs. 13 and 14 are details of the hub for the furrow-wheel. Y

The plow is of the three-wheel ty e, having two furrow and one land wheels, t e furrowwheels being carried at the end of a curved main beam A, the tongue'being pivoted at the middle of the beam to the center o'fa semicircular casting which is secured to one side oi the beam. The disk is carried upon a wedge-shaped abutment securedto the other side of the beam. Pivotally mounted upon the semicircularcasting is a reversing-cam having operative connection with the disk support or holder and acting to reverse the disk'when the tongue is swun around.

Referring specifically to t e drawings, 1-

indicates the reversing-cam referred to. This is ivoted upon a boss 2 at the center of the ha c1rcle casting 3. The cant-piece 1 turned the castin follows. and the disk is reversed. Natural y the tongue will swing at the same time; but the motionis not necessarily produced by the swin of the tongue. The seat-standard 4 is bolter upon the campiece 1.

To look the tongue and cam-piece together and to hold the tongue secure to the frame or beam, a foot-latch 10 is employed. This is pivoted to the tongue at 10 and has at each side depending wings or projections contain ing notches 10 which are arranged to respectively engage over or around one of the pins 11, projecting from the beam on oppoin or site sides of the central half-circle. A stud 12 also projects backwardly at the middie of the foot-latch and engages in a slot 12 at the front end of the cam-piece 1. When the latch is engaged with one of the pins 11 and the stud 12 is engaged in the slot in the front end of the cam-piece 1, said pieces are all looked together in position to plow.

When it is desired to release or reverse the plow, the foot-latch 10 is kicked forwardly, swinging its lower end out of contact with the pin 11 and also lifting the catch 12 from the slot in the end of the cam-casting 1. Then the team and tongue may be swung around on the central pivot'2, the connections Tacting'to carry the cam-plate around quite indeendent of the tongue, However, the footatch 10 releases the pin 1.1 before the catch 12 leaves the slot in the front end of the camcasting, so that the tongue will turn the cam, if it be desired, but by kicking the ioot'latch clear forward the rods act to reverse the cam. Both the camcasting and the tongue turn on the boss 2 when reversing.

In the rear end of the foot of the seat standard 4 is an undercut slot 53, which receives the beveled head of a boit 16, which The cainiece 1 rests upon At its forward end the tion With a frame having a wedge-shaped f abutment thereon formed of two spaced arms which meet at the point, of a low-support pivoted on said abutment an having a slot t erein, and a-scraper-standard also pivoted onsaid abutment'and havingits inner end projecting through said slot between'the arms and arranged to strike the sam'e't'o reverse the scra er. t

7 The com inationwith' a disk plow, of a scraper-arm supported on the frame of the low and overhanging the disk, a sleeve 'nged to the outer end of the arm, and a rod rotatable in said sleeve and carrying a scraperblade in contact with .the disk.

8. In a reversible plow, the combination I with furrow-wheels having turning-axles at the endsof the plow-beam, of an equalizingbar connected to said axles and having an extension, a disk-reversing element pivoted on the low frame, and a slot-and-bolt connection etween said element and said extension.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
